Located on a hill on the castle grounds, Wawel Cathedral is worth checking out when in Krakow. From Old Town, you have to go up a ramp, to enter the premises.
Dating back to the Middle Ages, the cathedral has gone through some changes over the centuries. The exterior is very nice to look at, and worth the time to see. Inside, the main part of the church is free, where you can walk around and see the nave and chapels through the place. This was where Pope John Paul II was bishop at one point.
The parts that requires a ticket, is to see the Sigismund Bell and the royal tombs.
First, with the Sigismund Bell, you have to climb some tight, wooden stairs. Some people may have a hard time getting through, as doorways are very small. Once you get to the bell, you see how big it is, and can stand under it. And get an okay view of Old Town, although there is a fence that makes it hard to take good pictures. And probably the only view in the offseason.
Second, the royal tombs, where it's basically who's who in Polish history, is buried. They include war heroes, kings and queens.
There is a separate building, where you buy a ticket. And you get can a combo ticket of the cathedral itself, and the museum.
A nice place to check out, as it is steeped in Polish history. But the view of the town, can be a bit of a letdown.
